maf to map?
 

how would one go from a maf to a map so that a na car could be turboed?
i found this but it dosen't make much sense
http://www.idaautomotive.com/changin..._a_map_sen.htm

also would in a honda the map is in the throttle body right?
because if so would it be possible to just swap throttle bodies (because the stocker is tiny as ----)
to gain airflow and be able to use a map so i can boost?
also for 8-12psi would a 2 bar map be adequit? (i belive i read that a 1 bar reds up to like 10.5 and 2 bar is like 22psi or somthing?)
anyway i found 2 bar map's for like $30-50 on ebay brand new

thanks for the help

Re: maf to map?
 

Yes you can go from maf to map. What motor set up is this?

Re: maf to map?
 

e-tec 2
1.6L dohc 103hp 107ft-lbs
6500rpm redline 6750 fuel cutoff
2005 aveo 5 speed

Re: maf to map?
 

I dont know what kind of ems systems they have for aveo's. but my brother went from a maf to a map on his eclipse. But he is running a aem ems standalone. Totally got rid of his stock computer.

Re: maf to map?
 

I think if you were to just put the maf in the charge pipe it would see boost, and you would be good to go!!!

Re: maf to map?
 

so your saying relocate the maf to the intake pipes instead of the intake manny so it reads the boost as a ---- tonne of vac?

that makes sence and the conputer already knows how to compensate for vacc as it is na but would i have to run larger injectors i am only looking for about 8-10psi maby 12 tops but as it's a stock engine with 105k i was just going to replace the stock hg with 2 mls hg's (stock comp is 9.5:1 so 2 stacked mls should bring it arround 8.6-8.8:1 and will be stronger than the stock, and while im at i i would want to go with arp studs, or would i just be better to go with arp studs and change them out one at a time so i don't have to pull the head?)

thanks for the help i have been getting flamed so much for wanting to turbo an aveo (i even got threatening pm's from some guy on here)

Re: maf to map?
 

one last thing, dose the maf read vac or air density?
if it measures vac then how do i know what it's reading limits are?
if it measures density then won't i need to have some way of "fattening up the mixture" as the revs build to compensate for boost?

i am sorry to sound like such a newb but i nave never worked with a turbo on a car that was not turbo stock

also i am looking for like 300-350cc injectors but i know they don't make them aveo specific (no aftermarket) but is there any out there that are similar enough to work?

Re: maf to map?
 

megasquirt FTW. I know youre not boosting that Aveo.. Or are you?

Re: maf to map?
 

no i really am boosting an aveo. or more like trying to, but i feel pretty confident i will get this figured out and running
but i admit i couldn't do it without hmt's help

Re: maf to map?
 

no, I would put the maf in the charge pipes, not the intake. charge pipes go in between your turbo and your throtle body.

Re: maf to map?
 

but wouldn't the maf not be able to read the boost to compensate for it and make it run lean as ---- till it blows?
also how bad are fmu's?

Re: maf to map?
 

all I know is alot of the nissan guys that are n/a, put it in the charge pipe side and it seems to work out tits.

Re: maf to map?
 

cool, i appriciate the help and will be sure to make a thread when i get the build started (hoping to start arround june and be finished in 1 weekend as the car is his dd)

also did the guys get their ecu chipped? as there is not chip out there for the aveo and i don't know if it can be re programed

Re: maf to map?
 

You need to do some damn research on your own. You make a thread about every single aspect of this turbo kit asking how to do it :l

chill

i was just asking because this is the first i have heard of using a maf on a boosted engine
so i was asking about the ecu big ------- deal

Re: maf to map?
 

well i should just kill myself then right?

seriously dude lighten the ---- up

Re: maf to map?
 

Yes.

Yes you should.

Re: maf to map?
 

#1: You have to place the maf between the turbo and the intake so it can read the Mass Air Flow (hence MAF).
#2: If you are going to run larger injecotrs, the MAF has to be calibrated for the larger injectors.
#3: In order to properly tune this without going stand alone, your going to need to be able to modify the computers programming.
#4: Since your friend does not like to change oil, even if you accomplish this and have it tuned properly, it will die soon.
#5: Your friend will blame you for the engine dying, and you will lose said friend.
#6: Fist yourself.


That is all.

Re: maf to map?
 

You really are clueless then. Just go to a forum that deals with performance on a type of car that uses a MAF, like Nissan, and it will most likely be a sticky in their forums. "Boosting with a MAF"

Re: maf to map?
 

thanks, but all i read on here is boosting hondas so i fell it's undertandable anything other than a honda is alien here (in general, not everyone on here has a honda is what i am saying)

Re: maf to map?
 

Your grammar is piss poor and you are not making sense. You are saying that non-Hondas are alien and then that not everyone on here has a Honda. I might be moving to the "ban cornfuzed" party

Re: maf to map?
 

no i said that hondas on here are common as niggs on welfair

Re: maf to map?
 

ok, cornfuzed, your a ------- idiot, go kill yourself...............

blow through = MAF in the charge pipe, it doesnt "read" boost, it "reads" FLOW, so it doesnt matter that its boosted, obviously its got a ceiling as to what it can "read", this generally is done because a BOV (to atmosphere) can be placed between the turbo and MAF and ait vented wont be "read/metered"
draw through = MAF is placed BEFORE the compressor inlet on the turbo, generally VE wont be as "skewed", which can happen slightly when going blow through... also this is how MOST factory boosted MAF'd cars are setup... like DSM's, SR20's, MR2 turbo, etc... the downfall is that you cant vent to atmosphere, rather the BOV needs to be re-circulated between the compressor inlet AFTER the maf...

go die in a fire, your gonna blow this aveo up if you didnt ALREADY understand the above, converting to map will require a "MAPECU" which is just a piggyback that uses a MAP and calculates the VE, this is retarded, other than that you will need to convert to a FULL standalone that will replace the ECU, like a AEM EMS, which probably isnt made for your application, so good luck finding a solution for a problem that shouldnt exsist....

go fist yourself.

Re: maf to map?
 

thanks for the first half where you were helpful as for finding a solution for a problem that shouldn't exsist i don't think i will have a problem as i found a daewoo forum (daewoo built the aveo and sold it for a couple years over seas then sold it to gm) where there are a few kalos (the daewoo's version of the aveo) that are running upwards of 175-190whp on stock internals with just a turbo setup running between 8-14psi
only problem is there is only 1 aftermarket clutch avalable for the aveo and it's only rated for up to 150ft-lbs and at 175hp your looking at like 180-185wft-lbs
